I was wondering how many similarities there were between the '00-spec LD9 and the L61and what parts can be interchanged.. I know the j underwent alot of changes in '00 with the firewall-mounted PCM, the BCM under the dash, the Getrag manual trannys (and the rear trans mount set farther back in the engine bay), etc..
* would the PCMs interchange, or are they motor specific?
* would aftermarket parts like urethane mounts, CAIs, and other parts be swappable?
* is the downpipe on the 2.4 the same style as the Ecotec (with the cat part of the downpipe, and the oddly-shaped oval flange connecting the rest of the exhaust)?

Nothing is really interchangeable...
I know some people got the 2.4 intake to work on a 2.2 eco... I also know some people used the 2.4 Upper mount too (before and eco one was available) thats about it

use the search feature
pretty sure its a 2.4 ECO intake they got to work not an LD9
2.4 PCM is the same as the 2200 just the program is different
the upper mount is different
the down pipe (not 100% sure but think its different
basically get a donor and do the swap an eco on a 2000+ is easier then a 99 and older
JBO since July 30, 2001
I really dont think he even knew there was a 2.4 eco... thats why he stated 2000 Spec 2.4
SOME people got the 2.4 LD9 aem intake to work on an eco (I had to clarify)

1. I doubt it, you could see if you could get it re-programmed at a dealer for an eco using a vin from an eco car, but I don't think it'll work.
2. only for non-engine related parts. though, the AEM as stated above supposedly can work. but I couldn't see how the upper engine mounts could. they're completely different.
3. No chance. we've already tried this and failed. it was quite sad when we were trying to put it on with me lying under the car swearing up a storm. cold cement floors + tranny and coolant everywhere = one pissed off me.
they both have 16 valves and 4 cylinders.. and use spark plugs( not the same) and have their fuel electronically injected..
similarities end there..
the 2.4 upper mount does fit... but the engine has a slight tilt to it (i blew out my stock eco mount and ran a 2.4 upper mount on the car for a bit.) lower mount will work as it hasn't changed from 95+
2.4 intakes do work but the ebay one i had (before the eco intakes were avail) rubbed the hood. it'd be easier to grab an intake made for the eco
I shoulda been a lil more clear, but I was really tired when I wrote that up there...
Qwibby, I am fully aware of the 2.4 Ecotec.. when I said the "2000-spec LD9", I was referring to the fact that the LD9s from '00+ (also heard the 99s were included) were different from the '96-'99 versions... the part I was wrong about was the fact that I thought that all '00+ j-bodies ran their PCMs on the firewall, and ran BCMs under the dash where the old ABS comps sat... I went to check out a '01 Z24 and found out differently and was later informed that that was a '02-'05 thing
the reason I was asking these questions is 'cause I've decided to sell my car.. a '98 Z24 that I swapped an Ecotec (L61) into.. and a friend of mine who's interested in buying it wants me to swap out some parts.. like the AEM CAI (I informed him of the horror stories of hitting puddles and locking up motors), the full exhaust (Pacesetter header, 2.5" all the way back to a 2.5" thru-n-thru muffler) 'cause its too loud.. and rather than hunt down new parts for him, I figured I'd take the parts off of this '01 Z24 (if I do end up buying it) and swap them out with my old Ecotec parts that he doesnt want, so I was wanting to see how possible some of this is.... and from the look of it, I'm gonna need to track down an Ecotec downpipe.. and the intakes swapping out looks iffy
I appreciate everyone's help, and if anyone else has any input, its more than welcome

I'll correct a few errors here...
As far as engines go.. the 2.4L was essentially the same from 96-98 and 99-02. The head, pistons, injectors, knock sensor, tensioner, etc changed in 99. EGR was deleted. Intake and exhaust manifolds changed slightly.
The PCM itself (but not the programming) is the same on all 00-02 2.4L cars... it's still in the front corner of the passenger side bumper area. It didn't move to the firewall until the Ecotecs came out.. The connectors are entirely different from a 2.4L. You couldn't use the Ecotec PCM on a 2.4L Twin Cam without rewiring the whole works. Not worth it, there's no gains to be seen here.
2000 was a major upgrade year. That's when all J-bodies (2.2L and 2.4L) moved from UART serial communication to "Class 2" wiring protocols. Basically... the Body Control Module controls everything in the car's body now. The ABS module under the dash on 95-99 cars got consolidated with the master cylinder, so it's one piece in 2000+ cars (and 03-05 with ABS, as it was again an option..). The convenience centre on the passenger side of the dash on a 95-99 car is essentially what became the BCM.. also has the receiver for the keyless entry rolled into it (if car is so equipped).
But in the end... very little swaps between the 2.4L and the 2.2L Eco engines in a J-car aside from the mounts.
damn lenko....even I learned something there haha

miracles happen every day.
But that is some good info.
yea man, that was alot of info to take in but I really appreciate it... I wasnt trying to swap the PCMs or anything crazy like that.. I was mainly wondering about the CAI and maybe the header.. I pretty much knew the header was a long shot but I thought the intake might've been close enough
weird how the car is set up so differenly from the 2.4 to the Ecotec... when you say that the LD9s were changed alot in 99, is that to say that they are better performance-wise?

I have a parts-specific question.. I know some of you guys said that the intakes between the 2 are different, but a friend was looking at his engine and mine and thinks that my intake might fit since its the FULL cold-air kit and not just a short-ram.. mine being an AEM true cold-air with the expansion pipe, would it fit on an LD9?

It might, but the fact that it is a cold air compared to a warm air, is more unlikely. Sell your intake and use that money to buy a new warm air off ebay.
